Application led August 24, `1916. `Serial No. 116,693.

To all whom it may concern:

Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements'in l/Vindow or Door Frame Shields; and Ido declare the following to be a full, clear, and exact description of the invention,suchas will enable others skilled in the arttowwhich it appertains to make and use the same. f

This invention relates to certain new and useful improvements in shields for window or door frames through which heavy articles such as coal, wood, etc., are tobe passed, but it is not restricted to such use as it may be employed in any connection for which it may be found appropriate.

The primary object of the invention isto.

provide a device of this character which is adjustable to ywindow or door frames, or the like, of all sizes.

Another object of the invention is to generally improve upon devices of this character by the provision of a device which will be extremely simple, durable and inexpensive in construction, one which may be easily and A readily attached to or detached from the window or door frame, and one which will be well adaptedto the purpose for which it is designed.

With these and otherobjects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings, forming part of the application, and in which similar reference characters designate like parts throughout the several views,

Figure lis aside elevation of a shield constructed in accordance with my invention and applied to a window frame;

Fig. 2 is a verticallongitudinal section of the parts shown in Fig. l; and

Fig. 3, is a vertical transverse section on the plane of the line 3-3 of Fig. 2.

Referring more particularly to the drawings, the letter A designates a window opening in which is mounted in the usual manner a casing or'frame B, and fitted to and within the casing orfframe B is a shield C constructed 1n accordance with this invention.

This shield or detachable frame is made adi justable both `vertically and horizontallyto fit window and door frames of any size each other.

within the limit of its adjustment, and is Beit known that I, WILLIAM F. BowMAN, a citizen ofthe United States, residing lat' extend in opposite directions and are disposed one upon the other, and are provided with means for slidably connecting the same to each other, thereby forming the. longitudinally adjustable sides of the window shield or detachable frame. The channels formed between theiianges 2 of the right angular members or strips l form, when the latter are assembled, a channel extending completely around the outer edge of the frame. The means preferably to be employed for slidably connecting the adjacent arms of the members together consists of rolling the free edges of the flanges outwardly upon themselves as at 3. The rolled portion 3 of one flange is made a trifle smaller than the rolled portion 3 of the adjacent flange so that the former will be snugly received and slidably mounted within the latter.

The means for locking the arms of the strips or members in their adjusted positions comprises U-shaped clamp members l which are disposed around the outer sides of the larger rolled portions 3 of the flanges. These clamp members l are provided with clamping bolts 5 extending through one side of the same, the inner endsl of which engage the outer sides 0f the rolled portions of the flanges and press the same into contact with Other means for accomplishing this same result may be employed if desired.

` In using the device the arms of the members are moved longitudinally relative to each other so as to contract the frame in or- `der that the same may be inserted within opening, the frame of the same will not be s marred r injured in any manner, as the detachable frame or shield will protect it.

From the forego-ing description, taken 1n connection with the accompanying `drawings, the vconstruction and use of the device f \will be readily understood without a more prising an open rectangular frame composed voi four right angular strips having flanges extending l laterally outwardly, from r'the edges thereof and formed integral with the same, the arms of the adjacent strips extending in opposite directions and disposed one upon the other, the vfree edges of said flanges being rolled upon themselves, the rolled por-V Copies of this patent may be obtained for tion of one flange being received and slidably mounted within Vthe rolled portion of arms of the adjacent members extending in opposite directions and disposed in' overlapping relation, and slidably connected together, said members having channels .in their outer edges to provide a window and door frame receiving channelV extending completely around the outer edge of the frame, and means for lockingthe arms of said members in their relatively adjusted positions.V 'p

In testimony whereof I-ha've hereunto set my hand in the presence of two subscribing witnesses.y

WILLIAM F; BowMAN.
